Anthropology 5 Problem Set # 1 To do this problem set you should have attended the first lecture and read Chapter 1 in the textbook (Boyd & Silk 2006). 1. Living things are complex, integrated, well adapted to their environments and capable of reproducing. At present, the theory of evolution by natural selection is the best scientific explanation for that state of affairs. Detail the six logical steps of the theory. The First step of the theory is that reproduction is exponential, meaning that a population can grow tremendously large over a few generations because offspring continue to have more offspring and their offspring do the same. The Second step states that numbers of organisms tend to be relatively stable in nature, meaning that a population will not continue to grow forever because it will reach its environment’s carrying capacity and once it overshoots its capacity the population will die off until it’s at a certain amount. This also leads into the Third step, which states that because numbers remain relatively stable, many individuals must fail to reproduce, they just live life with having any offspring. The Fourth step is essentially natural selection since it states that individuals with advantageous traits are more likely to survive and reproduce. An advantageous trait is one which promotes the ability to reproduce, so more offspring with the ability to reproduce will be born than those who cannot.
